- electrical conduits and has foritsobject-to pear in the following description, it being provide a strong, durable and thoroughly.

eflicient device of this character in which the pipe sect1ons are clamped within the box without the necessity of threading said sec- .tions or without the employment of nuts,

11 of cache amping member is a log 14 havolips and similar fastening devices.

A further object of the invention is to provide a conduit box including an elongated body portion having its opposite ends provided with. split clamping members pierced by alined openings for the reception of the adjacent conduit sections, said sections being locked within the box by contracting the clam ing members-at the split ends thereof.

A rther object is to provide the clamping members with inwardly extending lugs which form supports for the cover or closure of the box.

A still further object of the invention is generally to improve this class of'devices so as to increase their utility, durability and v l .pipe sections m the. openings .8 and adjusting eiliciency,

Further ob ects and advantages will apunderstood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming .a part ofthisspecification: Figure l is a per spective View of a conduit box constructed in accordance with my invention; Fig. 2 is ably formed integralittrerewith are spaced a side elevation of the same. Fig. .3 is a transverse sectional view.

,S1m1lar numerals of reference indicate corresponding parts all of the figures of the p drawings.

The improved sub'ect matter of the present invention inclu cs an elongated body portion 5 preferably curved or bowed in cross section, as

shown, and having its lower face flattened at 6 to assist in preventing tiltin movement Extending vertically om the opclamping members 7 having 'alined openings conduit box forming. the

8 formed therein. for the reception of the ends of the adjacent conduit sections 9. The clamping members 7 are substantially U shaped in form and are each split longitudinally at 10 to form spaced clam ing arms 11, the split portion being extende from the adjacent opening 8 to the top of the clamping member, as shown. The opposite longitudinal edges of the, body ortion 5 terminate here to form shoulders 12 adapted to receive and support the adjacent edges of a removable oover or closure 13.

Extendin inwardly from one of the arms ing an opening or erforation 15 formed therein the'wall's of whichare threaded for engagement with a screw or similarfastening device 16 which serves to secure the cover in position'on the conduit box.

The clamping arms 1 1 are pierced by transversely alined o enings 17 adapted to receive a bol-t 1 8 t e threaded end of which is engaged by a nut 19 so that by adjusting the at the split portion 10 may be forced in engagement with the adjacent conduit sections the conduit box.

It will thus be seen that by inserting the the nuts on the bolts 18 the conduit sections may be rigidly combined with the box with out the necessity of threading saidsection's and. without the employment of clips, bushin s, packing rings and similar devices.

n order to obtain access to the interior of the box it is merely necessary to remove the screws 16 when the cover or closure 13 may be lifted off the box so as to expose. the wires or other electrical conductors.

The conduitboxes may be made in different sizes and shapes and if desired the walls of the openings 8 may be rovided with a ackingrin or gasket to assist in preventing accidental .isplacement of the conduit sections.

' Havin thus described the invention what is claime is:

1. A conduit box including a body portion, split clamping members secured to the opposlte ends of the body portion and havmg o enin 's formed therein for the reception of t e on s of the adjacent conduit sections, di-

agonall I inwardl y from the clamping members, means short of the upper ends 0 the clamping memso nut on the bolt the free ends of the arms 11 9 and thus securely lock said sections within disposed perforated lugs extending for clamping said members in engagement with the conduit sections, a cover interposed between the clamping members and resting on said lugs and fastening devices extending through the cover and engaging the perfora-' tions in the lugs-for locking the cover in position on the box.

2. Aconduit box including a body portion having its side walls cut away to form longitudinal shoulders and its opposite ends rovidedv with clamping members exten ing above the shoulders andv having openings formed therein for the reception of the'ends of-the adjacent conduit sections, said clamping members being split longitudinally to form co-acting arms, acover interposed betweenthe clamping members and resting on said shoulders and a bolt piercing the arms for clamping the latter-in engagement with I the conduit sections.

'3'. A conduit box including a'body ortioncurved transversely and provided wit op 0-- sitely disposed clamping members exten ed vertically above the longitudinal edges of the 7 members at the split portions thereof for clamping said members in engagement with the conduit sections.

4Q A conduit box including an elongated body portion. having longitudinally split clamping members extending verticallyfrom the, opposite ends of the body ortion and projecting above the adjacent ongitudinal edges of the body portion to form an inter-' "mediate recess, said clamping members hav ing openings formed therein for the reeep tion of the ends of the adjacent conduit sections, lugs projecting inwardly from the clamping members, a cover resting on the adjacent longitudinal edges of the body portion and forming a closure for the recess, and

means extending transversely through the clamping members at the split portion there of for clamping said members in engagement with the conduit sections. 5.- A conduit box including an elongated body portion curved transversely in cross 7 section and provided with a flattened base,

substantially Us shaped clamping members extending vertically from the opposite ends of the body portion and projecting above the adjacent longitudinal ed es thereof, there bemg'openings formed in the clamping members for the reception of the ends of the adjacent conduit sections and having vertical slots extending from the tops of the clamping .members and intersecting the openings to form clamping arms, fastening devices piercing said arms for clamping the latter 1n engagement with the conduit sections, a lug extending inwardly 'from one arm of eachc'lamping member, a removable cover having its upper portion resting on the lugs and its lower adjacent edges of the body portion, and fasteningdevices' extendingthrough the cover and engaging the lugs for locking the cover against accidental displacement.

In testimony that we claim he foregoing as our own, we have hereto affixed our signatures in the presence of twowitnesses.
